Adding public SSH key to a git repository-CodePudding

To practice git I made the gituser create a bare repository in the directory /home/gituser/project.git. I later created a new user on my computer name Tom and I created sshkeys for it the ssh keys are stored in /home/Tom/.ssh directory. How would I be able to add the user Tom's public ssh key to gituser's repository so that Tom can commit and push changes to the repository? Both of the users have admin permissions on ubuntu 20.04 and only the gituser is in a group:dev. Note that both the users are on the same computer.

I know that the command to copy your public keys is :

ssh-copy-id -i ~/.ssh/id_rsa.pub <server>

but I am confused on what I can place for the server.

Outputs for gituser:

gituser@D-82I:~$ cd .ssh
-bash: cd: .ssh: No such file or directory
gituser@D-82I:~$ pwd
/home/gituser
gituser@D-82I:~$ ls
project.git
gituser@D-82I:~$ cd project.git/
gituser@D-82I:~/project.git$ ls
HEAD  branches  config  description  hooks  info  objects  refs

Outputs for user Tom and Errors:

Tom@DESKTOP-AVNQ82I:~$ ls
Tom@DESKTOP-AVNQ82I:~$ pwd
/home/Tom
Tom@DESKTOP-AVNQ82I:~$ cd .ssh
Tom@DESKTOP-AVNQ82I:~/.ssh$ ls
id_rsa  id_rsa.pub
Tom@DESKTOP-AVNQ82I:~/.ssh$ ssh-copy-id -i ~/.ssh/id_rsa.pub ~gituser/.ssh/authorized_keys
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/Tom/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

/usr/bin/ssh-copy-id: ERROR: ssh: Could not resolve hostname /home/gituser/.ssh/authorized_keys: Name or service not known
Tom@DESKTOP-AVNQ82I:~$ git remote add origin gituser@serverName:/home/gituser/project.git
fatal: not a git repository (or any of the parent directories): .git

CodePudding user response：

server should be:

the remote user account gituser which created the bare repo
the remote server hostname or IP address where the repo was created.

That means server:~gituser/.ssh/authorized_keys will receive Tom public SSH key.

From Tom's workstation, you can add the remote URL to your local repository:

git remote add origin gituser@serverName:/home/gituser/project.git

And push to it.
